TiO2 nanostructures have attracted an increasing attention as promising candidates in photocatalysis. In order to define their versatile function in light-induced photocatalysis, numerous attempts have been performed to overcome the inherent limitation due to its low bandgap energy. In this regard, it is an important task to modify the physical properties of TiO2 nanostructures with controlled structure and composition that are active under visible light. To this end, herein various approaches to prepare hybrid nanostructures such as carbon/TiO2 and metal/TiO2 with various configurations utilizing block copolymer (BCP) as template were introduced. Thin film type hybrid TiO2 nanostructures were prepared on planar Si wafer and silica bead surfaces. The surface morphologies, optical and visible light active photocatalytic properties of prepared samples were investigated by AFM, SEM, TEM, and UV-vis spectroscopy. |
